Lithium secondary battery including a nonaqueous electrolyte containing a compound represented by LiO3S—R—SO3Li and method of manufacturing the same
摘要:
A method including a step of preparing a positive electrode including a positive electrode mixture layer, a negative electrode including a negative electrode mixture layer, and a nonaqueous electrolyte; and a step of accommodating the positive electrode, the negative electrode, and the nonaqueous electrolyte in a battery case. The nonaqueous electrolyte contains a compound (I) represented by the following formula (I) LiO3S—R—SO3Li (wherein R represents a linear hydrocarbon group having 1 to 10 carbon atoms). When a BET specific surface area of the negative electrode mixture layer is represented by X (m2/g) and when an amount of the compound (I) with respect to the total amount of the nonaqueous electrolyte is represented by Y (mass %), the following relationships 3≤X≤4.3, 0.2≤Y≤0.4, and (Y/X)≤0.093 are satisfied.
